To reach the efficiency goal in this PSFB design, careful consideration needs to be taken in selecting electrical components. The devices need to be selected based voltage rating, current rating and power dissipation. The initial step in this design process is to set a power budget (PBUDGET) which the total losses of the electrical components selected for the design cannot exceed.
